    Nanoscale View Article Online PAPER View Journal | View Issue Large-area tungsten disulfide for ultrafast photonics Cite this: Nanoscale, 2017, 9, 1871 Peiguang Yan,*a Hao Chen,a Jinde Yin,a Zihan Xu,b Jiarong Li,a Zike Jiang,a Wenfei Zhang,a Jinzhang Wang,a Irene Ling Li,a Zhipei Sunc and Shuangchen Ruan*a Two-dimensional (2D) layered transition metal dichalcogenides (TMDs) have attracted significant interest in various optoelectronic applications due to their excellent nonlinear optical properties. One of the most important applications of TMDs is to be employed as an extraordinary optical modulation material (e.g., the saturable absorber (SA)) in ultrafast photonics. The main challenge arises while embedding TMDs into fiber laser systems to generate ultrafast pulse trains and thus constraints their practical applications. Herein, few-layered WS2 with a large-area was directly transferred on the facet of the pigtail and acted as a SA for erbium-doped fiber laser (EDFL) systems. In our study, WS2 SA exhibited remarkable nonlinear optical properties (e.g., modulation depth of 15.1% and saturable intensity of 157.6 MW cm−2) and was Creative Commons Attribution 3.0 Unported Licence. used for ultrafast pulse generation. The soliton pulses with remarkable performances (e.g., ultrashort pulse duration of 1.49 ps, high stability of 71.8 dB, and large pulse average output power of 62.5 mW) Received 25th November 2016, could be obtained in a telecommunication band. To the best of our knowledge, the average output Accepted 29th December 2016 power of the mode-locked pulse trains is the highest by employing TMD materials in fiber laser systems.

It necessitates selective and energy-efficient electrocatalystsa requirement met today only using noble metals such as gold and silver. Here, we show that the two-dimensional sulfur planes in semimetallic fi titanium disul de (TiS2) provide an earth-abundant alternative. In situ Fourier transform infrared mechanistic studies reveal fi − that CO2 binds to conductive disul de planes as intermediate monothiocarbonate. The sulfur CO2 intermediate state steers fi ffi 2 the reduction kinetics toward mainly CO. Using TiS2 thin lms, we reach cathodic energy e ciencies up to 64% at 5 mA cm . We conclude with directions for the further synthesis and study of semimetallic disulfides developing CO-selective electrocatalysts. fi KEYWORDS: CO2 reduction reaction, titanium disul de, electrocatalysis ■ INTRODUCTION conductivity similar to that of graphite.29,30 We show here that TiS2 can enhance CO2 reduction because a major limitation in Electrocatalysis is an attractive pathway to recycle CO2, upgrading it using renewable energy.1 Presently, the electro- earlier used MoS2 and related materials, the poor electrical ffi conductivity, is resolved.

SUMMARY: This policy document, issued by the New York State Department of Environmental Conservation (NYSDEC), outlines the procedures for evaluating the emissions of criteria and non-criteria air contaminants from process operations in New York State. Incorporated within the policy document are three flow charts to aid the end user when identifying applicable process emission sources, establishing uniform Environmental Ratings (ER) and ascertaining the proper degree of control for applicable process emission sources. II. POLICY: This policy is written to provide guidance for the implementation of and compliance with 6 NYCRR Part 212 Process Operations (Part 212). III. PURPOSE AND BACKGROUND: This policy provides guidance for the control of criteria and toxic air contaminants emitted from process emission sources in New York State. Process emission sources refer to the equipment at 1 manufacturing facilities that result in the release of air contaminants during operation. Process emission sources do not include equipment that combust fuel for electricity or space heating for commercial, industrial plants or residential heating. The policy describes the Division of Air Resources’ (DAR) procedures for implementing Part 212. This policy replaces the DAR-1 previously issued on August 10, 2016 by DAR. This document provides guidance to NYSDEC staff, those facility owners subject to Part 212, and the general public.

    Synthesis of 2D Transition Metal Oxides Robert Michael Loh, Material Science and Engineering Mentor: Prof. Qing Hua Wang , Suneet Kale School for Engineering of Matter, Transport and Energy Abstract Exfoliation of HfS2 and PdSe2 CVD Synthesis Steps HfS2 • The goal of this FURI project is to synthesize thin film transition metal oxides. Metal oxides have known bulk properties but some have not been synthesized in a thin film forms. Materials take on vastly different properties when they are on the nano-scale. • Nanomaterials have been utilized in many ways such as batteries, insulation, medicine, transportation, and optics[1]. • The hypothesis of this project is that thin film transition metal oxides of germanium dioxide (GeO2), hafnium dioxide (HfO2), and palladium dioxide (PdO2) can be synthesized based on [2] previous research by the Wang research group . Their results show that molybdenum [5] trioxide (MoO3) and tungsten trioxide (WO3) can be synthesized from their respective sulfides MoS2 and WS2 by atmospheric plasma treatment in the form of thin-flake nanomaterials. First Semester Results Synthesis of HfS2 via Chemical Vapor Deposition Synthesis of GeS2 Flakes • Hafnium disulfide was also made using a method called chemical vapor deposition. • Referencing an article on material synthesis of thin flakes[3] mechanical exfoliation of A mixture of argon ( 50 sccm) and hydrogen (15 sccm) gas are passed into a tube GeS2 was found to be most favorable by plasma treating substrates to be hydrophilic furnace made of quarts at ambient pressure. They carry vaporized hafnium chloride and exposing samples to 100 oC heat for one minute before cleaving.
